How to Track Model and Prediction Lineage in Vertex AI?
You are developing a process for training and running your custom model in production. You need to be able to show lineage for your model and predictions. What should you do?

Community Insight
The question tests knowledge of Vertex AI lineage tracking capabilities, with the common trap being the confusion between Experiments (for hyperparameter tuning) and Pipelines (for artifact/prediction lineage).
Vertex AI Pipelines provide built-in artifact lineage tracking for model training and batch predictions using Vertex ML Metadata. The exam community strongly favors pipelines over experiments for end-to-end traceability in production workflows.
Option D (Vertex AI Experiments) is frequently chosen because it tracks training runs and metrics, but it lacks comprehensive artifact lineage for predictions and production pipeline components that Pipelines offer.

Why the Answer Is Correct
Vertex AI Pipelines automatically record artifact lineage through Vertex ML Metadata, capturing inputs, parameters, models, and outputs like predictions. When you run a pipeline, every component execution is logged, enabling full traceability from raw data to deployed model artifacts. This makes Pipelines the definitive tool for audit-ready lineage in production environments.Why the Other Options Are Wrong
Option A tracks dataset versions but does not capture model architecture changes or prediction lineage. Option C merely stores data without providing any metadata tracking or lineage capabilities. Option D focuses on comparing hyperparameters and metrics across multiple training runs rather than tracking production artifacts and prediction chains.Community Comment Notes
The community split heavily between B and D, reflecting a common certification dilemma. Commenters clarified that while Experiments track model versions and metrics, Pipelines are specifically designed for artifact lineage and prediction tracking (Comment #2, #3). Several users noted that the phrase 'running your custom model in production' strongly implies an orchestrated workflow, making Pipelines the correct architectural choice (Comment #10).Official Reference
Exam Strategy
When exam questions mention 'lineage,' 'artifact tracking,' or 'end-to-end workflows,' immediately select Vertex AI Pipelines over Experiments. Reserve Experiments for scenarios emphasizing hyperparameter tuning, metric comparison, or iterative model development rather than production audit trails.
